To all whom it may concern H Be it known that I, Osnsrnn E Micrmioo, a, citizen of the United States, and n resident of the city of St. Louis and State or Missouri, have invented a. new and useful 1m pinup may be driven from the crank shaft provement in Internal-Commotion Motors, through the medium of any suitable gearing, of which the following is specification. but preferably by a sprocket chain 18 pass- This invention relates to internal com} 7 1d the sprock t wheels 19 end 20 tion motors, and more par-tiers. irl ctively on the pump $11 .55 d of the four stroke or four cycle type. cramr Ithes for its principal objects to improve each "provided on op upon the inlet and exhaust velvesof such. v yd h t ports motors and the manner of operating the d thaTortS some, and to attain certni advantages which will hereinafter more fully appear. The invention consists in the parts and in the arrangements and combinations of parts o. \e

V cordance with the usual practice and has Cap pieces 27 provlded to secure the 'our-na/led therein a crank shaft 6 which valve members in place. These cap pieces isof the ordinary four throw type and is have semi-cylindrical portions in which the connected to the nesp'ective pistons 7 by valve members rotate and they are also rods 8. provided at their ends with grooves for the l ,6. cylinders have annular water spaces reception of the ribs 26.

The valve sections 24 and 25 have middle openings 28 which are adapted to communicats with supply and exhaust manifolds 29 and 30 respectively. These manifolds have upturned end portions to which are attached bearing members 31 having openings 32 so as to communicate with the openings 28 in said valve members. are secured to the bearin pieces 31 and said bearing members an cap pieces are provided with grooves at their ends adapted to receive the annular ribs 26 which are provided on opposite sides of the openings 28. These ribs 26 and those above mentioned which cooperate with the bosses 23 and cap pieces 27 serve as end thrust bearings for the valve members and also enable a tight joint being, made without a great amount of friction.

The companion valve members may be fastened so as to rotate together in any suitable manner, but it is preferable to provide a square groove in the end of one member in which is fitted a round rib or head on the other member so as to'permit an oscilla tory movement of one member with respect to the other and yet compel them to rotate in unison. The valve members are provided with extensions 34 on which are secured spur gears 35 meshing with an intermediate gear 36 mounted on a stub shaft 37. On this stub shaft is fixed a sprocket wheel 38 which is driven by a sprocket chain 39 running over a sprocket wheel 40 on the crank shaft of the motor. By this arrangement the intake and exhaust alves are rotated simultaneously and at the same speed which is at the ratio of two to one with respect to the crank shaft. That is, the crank shaft makes two revolutions for each'revolution of the valves. Or in other Words, the valves make one revolution during the four cycles of the pistons.

As above mentioned, the motor is of the four cycle type. Consequently the ports 24 and 25 respectively of the intake and exhaust valves must be brought into register with the intake and exhaust orts of the cylinder once in a complete cyc e. The cylinders are referably fired in the order of 1, 3, 4, 2. 'i hatis, the power strokes 6f the pistons of the cylinders follow in "bud cession in the order named. In Fig. 10

(cylinder No." 1) the piston is shown up In Fig. 9 (cylinder No. 2) the piston is shown down ready for the exhaust stroke. This last mentioned cylinder has fired just prior to the cylinder N o. 1.

Cap pieces 33 o. 3) the'piston is down ready for the The relative arrangement of the ports in the intake and exhaust valves will be varied so that oil is constantly supplied for the lubrication of the bearing without interfering with the combustible gases taken into the on he. The manifold may be connected wit a gravity supply tank (not shown) in any obvious manner.

Obviously, the motor admits of considerable modification without departing from the invention. Therefore, I do notwish to be limited to the specific constructions and arrangements shown.

What I claim is: 1. In an internal combustion motor, the

combination with a plurality of working cylinders arranged-in a row and having inlet and exhaust ports on op said cylinders having lateraprojections osite sides,

provided with horizontal semi-cylmdrical" valve seats into which the said orts respgctively open, rotatory tubular va ve mem rs each arranged to cooperate with two adjoi ing cylinders and fitted in said seats having ports corresponding to the ports the cylinders, said valve members having annular circumferential ribs on oppos te sides of the ports therein, separate cap pieces fitted over said tubular valve members and cooperating with the respective lateral projections of the cylinder to provide con-. tinuous bearings for said valve members,

said lateral projections and cap pieces having cotip'erating sem -circular grooves pro vidin continuous bearin for said annular ri s on the valve mem ers, said tubular valve members being closed at both ends and having ports at the middle, and a. manifold pipe having branches provided at their ends with sleeves which are fitted on saidvnlve members in the region of said middle ports.

2. In an internal combustion motor, the

combination with a battery of working'cyl inders arran ed in a row, saidzcylinders having aline intake portson one Side and exhaust ports on the opposite side, said c l inders also having semi-cylindrical va ve seats in the region of the respective pom, detachable cap pieces having counterpart valve-seats cooperating with said semi-cylindrical valve seats, cylindrical tubular valve members fitte'd rotatably in said valve seats, said tubular valve members having closed ends and each being of sufiicient length and having ports arranged to co operate with the joining working respective parts of two adcylinders said valve members having ports intermediate their ends,

and supply and extensions provi fitted rotatablv 0 exhaust manifnlds having ded wlth terminal sleeves n the respective valve memhere in the region of the intermediate ports therein and arranged and adapted to estab Witnesses:
